Don't worry Nole has not been using the Speed Pro. Here is Djokovic in Sydney before the 2009 Australian Open using the same 18x20 string pattern, same 21mm beam width, and the same classic oval head shape which is a Classic head design that he has always has used. Photo By viktorkwan Now Djokovic did make some tweaks to his layup because his racquet now have a stiffness of 51RA. I think that is the difference he had to adjust to. http://www.hdtennis.com/grs/pro_racquet_specs/2009bnp_paribas_open.html In Case you are wondering the real Speed Pro is 16x19 string pattern, 18mm beam width, a very round lolly-pop like head shape, with a stiffness of 70RA:shock:. Novak never used this racquet or mold.
